A new discovery in the field of physics, namely the discovery of X-rays by Professor Wilhelm Conrad Röntgen of Würzburg, has created a great stir in the scientific world. These rays, so called because their nature is still unknown, are produced by a vacuum tube and are capable of passing through opaque bodies, such as wood, flesh, and metals, and producing a visible effect on a phosphorescent screen. They are not reflected or refracted, and they do not affect the eye directly. They are capable of producing an image on a photographic plate, and it is by this means that they have been studied.

The discovery was made on November 8, 1895, by Professor Röntgen, who was experimenting with cathode rays. He noticed that a screen coated with barium platinocyanide, which was placed near the vacuum tube, began to glow when the tube was in operation. He found that this glow was not due to the cathode rays themselves, but to some other invisible radiation that was being produced by the tube. He called this radiation X-rays.

The X-rays have been found to have a variety of applications, including medical diagnosis, industrial inspection, and scientific research. In medicine, they are used to photograph the bones and internal organs of the body, and to detect diseases such as cancer and tuberculosis. In industry, they are used to inspect materials for defects, and to detect the presence of foreign objects. In scientific research, they are used to study the structure of atoms and molecules, and to investigate the properties of matter.

The discovery of X-rays is one of the most important scientific discoveries of the nineteenth century. It has had a profound impact on many fields of science and technology, and it is likely to continue to have a major impact in the years to come.
